Water-producing billboard

The city of Lima Peru doesn’t get much rainfall, but they can get humidity as high as 98%. The University of Engineering and Technology (UTEC) has partnered with advertising agency Mayo-Draft FCB to create a novel way for residents to not only get unpolluted drinking water (their local wells are often polluted), but also to show prospective students that they could make the world a better place by becoming an engineer. The billboard catches humidity in the air and turns it into filtered drinking water, and is capable of producing 96 liters (over 25 gallons) of water every day for the locals or travelers needing a drink.
